Cayenne's Automotive Tips from Allied Auto Works: Serpentine Belt Tensioner


Hi, Cayenne here, and today I have some tips for you regarding your Serpentine Belt Tensioner, so let's buckle up and bark into this subject now.

The serpentine belt tensioner applies pressure to the serpentine belt, maintaining optimal tension to drive the accessories like the alternator and A/C compressor. At Allied Auto Works, we know that the service life of the belt tensioner is the same as the belt itself, so they should always be replaced together. A worn tensioner prevents the accessories from spinning properly, leading to premature wear and noise for Los Altos drivers.

Your vehicle manufacturer has a recommended mileage interval for serpentine belt replacement. A complete accessory drive system service replaces the serpentine belt, the belt tensioner, and any idler pulleys your car might have. Your friendly and professional Allied Auto Works service advisor can inspect your system and let you know if it’s time for a replacement.

Give us a call today and tell them Cayenne sent you.

I leave you with my belt joke of the day,

"What do you call a belt made of $100 bills?   A waist of money"
